It's a fascinating piece of history that the coin we commonly call a "nickel" has a remarkably consistent composition. Before the pivotal year of 1942, when the demands of World War II forced a change, the United States five-cent piece was reliably crafted from a specific and durable alloy of 75% copper and 25% nickel. This has been the standard for the vast majority of the coin's existence.
This particular blend wasn't an accident; it was a deliberate choice made back in 1866. The coin was introduced to solve a major problem following the Civil War, a time when precious metals like silver and gold had all but vanished from public circulation. The country needed a sturdy five-cent coin to replace the flimsy paper currency of the era, and this robust copper-nickel alloy proved to be the perfect, long-lasting solution.
So, while the five-cent coin that existed before 1866 was a small silver piece known as the "half dime," the coin we recognize as the nickel has almost always been made of that classic 75/25 copper-nickel blend. From its introduction after the Civil War all the way up to the material shortages of WWII, you can be confident that the nickel was defined by its signature copper and nickel composition.
